20 Installation 10.Installation Safety ConsiderationsRead these SAFETY CONSIDERATIONS for Installation carefully before installing an air conditioner or heat pump. After completing the installation, make sure that the unit operates properly during the startup operation. Instruct the customer on how to operate and maintain the unit. Inform customers that they should store this Installation Manual with the Operation Manual for future reference. Always use a licensed installer or contractor to install this product. Improper installation can result in water or refrigerant leakage, electrical shock, fire, or explosion. Meanings of DANGER, WARNING, CAUTION, and NOTE Symbols: DANGER... Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING... Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. CAUTION... Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices. NOTE... Indicates situations that may result in equipment or property-damage accidents only. DANGER Refrigerant gas is heavier than air and replaces oxygen. A massive leak can lead to oxygen depletion, especially in basements, and an asphyxiation hazard could occur leading to serious injury or death. Do not ground units to water pipes, gas pipes, telephone wires, or lightning rods as incomplete grounding can cause a severe shock hazard resulting in severe injury or death. Additionally, grounding to gas pipes could cause a gas leak and potential explosion causing severe injury or death. If refrigerant gas leaks during installation, ventilate the area immediately. Refrigerant gas may produce toxic gas if it comes into contact with fire. Exposure to this gas could cause severe injury or death. After completing the installation work, check that the refrigerant gas does not leak throughout the system. Do not install unit in an area where flammable materials are present due to risk of explosions that can cause serious injury or death. Safely dispose all packing and transportation materials in accordance with federal/state/local laws or ordinances. Packing materials such as nails and other metal or wood parts, including plastic packing materials used for transportation may cause injuries or death by suffocation. Only qualified personnel must carry out the installation work. Installation must be done in accordance with this installation manual. Improper installation may result in water leakage, electric shock, or fire. When installing the unit in a small room, take measures to keep the refrigerant concentration from exceeding allowable safety limits. Excessive refrigerant leaks, in the event of an accident in a closed ambient space, can lead to oxygen deficiency. Use only specified accessories and parts for installation work. Failure to use specified parts may result in water leakage, electric shocks, fire, or the unit falling. Install the air conditioner or heat pump on a foundation strong enough that it can withstand the weight of the unit. A foundation of insufficient strength may result in the unit falling and causing injuries. Take into account strong winds, typhoons, or earthquakes when installing. Improper installation may result in the unit falling and causing accidents. Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried out by qualified personnel according to local. state, and national regulations. An insufficient power supply capacity or improper electrical construction may lead to electric shocks or fire. Make sure that all wiring is secured, that specified wires are used, and that no external forces act on the terminal connections or wires. Improper connections or installation may result in fire. When wiring, position the wires so that the terminal box lid can be securely fastened. Improper positioning of the terminal box lid may result in electric shocks, fire, or the terminals overheating. Before touching electrical parts, turn off the unit. This equipment can be installed with a Ground-Fault Circuit Breaker (GFCI). Although this is a recognized measure for additional protection, with the earthing system in North America, a dedicated GFCI is not necessary. Securely fasten the outside unit terminal cover (panel). If the terminal cover/panel is not installed properly, dust or water may enter the outside unit causing fire or electric shock. When installing or relocating the system, keep the refrigerant circuit free from substances other than the specified refrigerant (R-410A) such as air. Any presence of air or other foreign substance in the refrigerant circuit can cause an abnormal pressure rise or rupture, resulting in injury. Do not change the setting of the protection devices. If the pressure switch, thermal switch, or other protection device is shorted and operated forcibly, or parts other than those specified by Daikin are used, fire or explosion may occur. FXAQ-PVJU 19

21 Installation Do not touch the switch with wet fingers. Touching a switch with wet fingers can cause electric shock. Do not allow children to play on or around the unit to prevent injury. The heat exchanger fins are sharp enough to cut. To avoid injury wear gloves or cover the fins while working around them. Do not touch the refrigerant pipes during and immediately after operation as the refrigerant pipes may be hot or cold, depending on the condition of the refrigerant flowing through the refrigerant piping, compressor, and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the refrigerant pipes. To avoid injury, give the pipes time to return to normal temperature or, if you must touch them, be sure to wear proper gloves. Install drain piping to proper drainage. Improper drain piping may result in water leakage and property damage. Insulate piping to prevent condensation. Be careful when transporting the product. Do not turn off the power immediately after stopping operation. Always wait for at least 5 minutes before turning off the power. Otherwise, water leakage may occur. Do not use a charging cylinder. Using a charging cylinder may cause the refrigerant to deteriorate. Refrigerant R-410A in the system must be kept clean, dry, and tight. (a) Clean and Dry -- Foreign materials (including mineral oils such as SUNISO oil or moisture) should be prevented from getting into the system. (b) Tight -- R-410A does not contain any chlorine, does not destroy the ozone layer, and does not reduce the earth s protection again harmful ultraviolet radiation. R-410A can contribute to the greenhouse effect if it is released. Therefore take proper measures to check for the tightness of the refrigerant piping installation. Read the chapter Refrigerant Piping and follow the procedures. Since R-410A is a blend, the required additional refrigerant must be charged in its liquid state. If the refrigerant is charged in a state of gas, its composition can change and the system will not work properly. The indoor unit is for R-410A. See the catalog for indoor models that can be connected. Normal operation is not possible when connected to other units. Remote controller (wireless kit) transmitting distance can be shorter than expected in rooms with electronic fluorescent lamps (inverter or rapid start types). Install the indoor unit far away from fluorescent lamps as much as possible. Indoor units are for indoor installation only. Outdoor units can be installed either outdoors or indoors. This unit is for indoor use. Do not install the air conditioner or heat pump in the following locations: (a) Where a mineral oil mist or oil spray or vapor is produced, for example, in a kitchen. Plastic parts may deteriorate and fall off or result in water leakage. (b) Where corrosive gas, such as sulfurous acid gas, is produced. Corroding copper pipes or soldered parts may result in refrigerant leakage. (c) Near machinery emitting electromagnetic waves. Electromagnetic waves may disturb the operation of the control system and cause the unit to malfunction. (d) Where flammable gas may leak, where there is carbon fiber, or ignitable dust suspension in the air, or where volatile flammables such as thinner or gasoline are handled. Operating the unit in such conditions can cause a fire. Take adequate measures to prevent the outside unit from being used as a shelter by small animals. Small animals making contact with electrical parts can cause malfunctions, smoke, or fire. Instruct the customer to keep the area around the unit clean. Install the power supply and control wires for the indoor and outdoor units at least 3.5 feet away from televisions or radios to prevent image interference or noise. Depending on the radio waves, a distance of 3.5 feet may not be sufficient to eliminate the noise. Dismantling the unit, treatment of the refrigerant, oil and additional parts must be done in accordance with the relevant local, state, and national regulations. Do not use the following tools that are used with conventional refrigerants: gauge manifold, charge hose, gas leak detector, reverse flow check valve, refrigerant charge base, vacuum gauge, or refrigerant recovery equipment. If the conventional refrigerant and refrigerator oil are mixed in R-410A, the refrigerant may deteriorate. This air conditioner or heat pump is an appliance that should not be accessible to the general public. As design pressure is 478 psi, the wall thickness of field-installed pipes should be selected in accordance with the relevant local, state, and national regulations. 20 FXAQ-PVJU

22 Installation 2. BEFORE INSTALLATION When moving the unit while removing it from the packing case, be sure to lift it by the four hanger brackets. Aboid putting any pressure on other parts, especially, holizontal flaps, the refrigerant piping, drain piping, and other resin parts. Be sure to remove a cushion (corrugated paper) located between the heat exchanger and the right air filter. Be sure to check the type of R410A refrigerant to be used before installing the unit. (Using an incorrect refrigerant will prevent normal operation of the unit.) The accessories needed for installation must be retained in your custody until the installation work is completed. Do not discard them! Decide upon a line of transport. Leave the unit inside its packaging while moving, until reaching the installation site. Where unpacking is unavoidable, use a sling of soft material or protective plates together with a rope when lifting, to avoid damage or scratches to the unit. For the installation of an outdoor unit, refer to the installation manual attached to the outdoor unit. When using the wireless remote controller, refer to the installation manual attached to the wireless remote controller. Do not install or operate the unit in rooms mentioned below.

Execute heat insulation work completely on both sides of the gas piping and the liquid piping. Otherwise, a water leakage can result sometimes. (When using a heat pump, the temperature of the gas piping can reach up to approximately 250 F, so use insulation which is suffi ciently resistant.) Also, in cases where the temperature and humidity of the refrigerant piping sections might exceed 86 F or RH80 %, reinforce the refrigerant insulation. ( or thicker) Condensation may form on the surface of the insulating material. Before refrigerant piping work, check which type of refrigerant is used. Proper operation is not possible if the types of refrigerant are not the same. DANGER Refrigerant gas may produce toxic gas if it comes in contact with fire such as from a fan, heater, stove or cooking device. Exposure to this gas could result in severe injury or death. NOTE Use a pipe cutter and fl are suitable for the type of refrigerant. To prevent dust, moisture or other foreign matter from infiltrating the tube, either pinch the end or cover it with tape. Do not allow anything other than the designated refrigerant to get mixed into the refrigerant circuit, such as air, etc. If any refrigerant gas leaks while working on the unit, ventilate the room thoroughly right away. 28 FXAQ-PVJU

30 Installation The outdoor unit is charged with refrigerant. Use copper alloy seamless pipes. Be sure to use both a spanner and torque wrench together, as shown in the drawing, when connecting or disconnecting pipes to/from the unit. (Refer to Fig. 12) Refer to Table 1 for the dimensions of fl are. When connecting the fl are nut, coat the fl are section with ester oil or ether oil, rotate three or four times fi rst, then screw in. (Refer to Fig. 13) CAUTION Over-tightening may cause the fl are nuts to crack or the refrigerant to leak. Use the flare nut included with the unit. Refer to Table 1 for tightening torque.

After the work is finished, make sure to check that there is no gas leak. When you keep on tightening the fl are nut with a spanner, there is a point where the tightening torque suddenly increases. From that position, further tighten the flare nut the angle shown below: Table 2 Pipe size (in.) Further tightening angle Recommended arm length of tool (in.) φ 1/4 60 to 90 degrees Approx. 5-7/8 φ 3/8 60 to 90 degrees Approx. 7-7/8 φ 1/2 30 to 60 degrees Approx. 9-13/16 φ 5/8 30 to 60 degrees Approx /16 CAUTION CAUTION TO BE TAKEN WHEN BRAZING REFRIGERANT PIPING Do not use fl ux when brazing refrigerant piping. Therefore, use the phosphor copper brazing filter metal (BCuP) which does not require fl ux. (Flux has an extremely negative effect on refrigerant piping systems. For instance, if chlorine based flux is used, it will cause pipe corrosion. If the flux contains fluorine, it will damage the refrigerant oil.) FXAQ-PVJU 29

31 Installation When brazing the refrigerant piping, only begin brazing after having carried out nitrogen substitution (NOTE 1) or while inserting nitrogen into the refrigerant piping (NOTE 2). Once this is done, connect the indoor unit with a fl ared or a fl anged connection. DANGER Use of oxygen may cause an explosion resulting in serious injury or death. Only use nitrogen gas NOTE Refer to the Manual for Multi Installation for Buildings for directions on how to carry out nitrogen substitution. (Inquire with your dealer.) Nitrogen should be set to 2.9 psi with a pressure-reducing valve if brazing while inserting nitrogen into the piping. (Refer to Fig. 14) Refrigerant piping Part to be brazed Taping hands valve Pressure-reducing valve Nitrogen Nitrogen Fig. 14 After checking for gas leaks, be sure to insulate the pipe connections using the supplementary piping insulation tubing and insulating tape (4). The insulating tape (4) should be wrapped from the L-shaped bend all the way to the end inside the unit. (Refer to Fig. 15) Local piping Insulating tubing tape Clamping material large (accessory) (5) Insulating tubing tape Indoor unit piping insulation tubing Insulating tubing tape Indoor unit piping Indoor unit piping insulation tubing Insulating tape (accessory) (4) See 4.

32 Installation 10.3 Drain Piping Work 6. DRAIN PIPING WORK (1) Install the drain piping. (Refer to Fig. 16) The drain pipe should be short with a downward slope and should prevent air pockets from forming. Watch out for the points in the fi gure 16 when performing drain work. Make sure the drain hose is at a downward slope. Drain hose (Downward slope) Drain hose Make sure the tip does not go underwater even when water is added. Fig. 16 When extending the drain hose, use a commercially available drain extension hose, and be sure to insulate the extended section of the drain hose which is indoors. (Refer to Fig. 17) Indoor unit drain hose Extension drain piping (commercially available) Insulating tube (commercially available) Insulating tape (accessory) (4) ( See 4. INDOOR UNIT INSTALLATION ) Fig. 17 Make sure the diameter of the extension drain piping is the same as the indoor unit drain hose (hard vinyl chloride, I.D. 9/16 ) or bigger. In case of converging multiple drain pipes, install them referring to Fig. 18. Select diameter of drain piping which adapts to the capacity of the unit connected. 4 or more Fig. 18 (Slope of at least 1/100) (2) Make sure the drain works properly. After drain work is complete, perform a drain check by opening the front panel, removing the air filter, pouring water into the drain pan, and making sure water fl ows smoothly out of the drain hose. (Refer to Fig. 19) Plastic container for pouring Drain pan Fig. 19 Make sure not to splash the water. CAUTION Drain Piping Connections: Do not connect the drain piping directly to sewage pipes that smell of ammonia. The ammonia in the sewage might enter the indoor unit through the drain pipes and corrode the heat exchanger.. Never allow water to collect on the drain pipe or it will cause blockage. FXAQ-PVJU 31

35 Installation To avoid a short circuit in the control box, be sure to apply sealing material or putty (not included) to the wiring hole to prevent the infi ltration of water as well as insects or other small creatures. Otherwise a short-circuit may occur inside the control box. CAUTION When clamping the wirings, be sure no tension is applied to the wire connections by using the included clamp. Also, when wiring, make sure the cover on the control box fits snugly by arranging the wirings neatly and attaching the control box cover firmly. When attaching the control box cover, make sure no wirings get caught in the edges. Pass wiring through holes to prevent damage to them. Make sure the remote controller wiring and transmission wiring between the units, and other electrical wiring do not pass through the same locations outside the unit, separating them by at least 5, otherwise electrical noise (external static) could cause incorrect operation or breakage. Use only specifi ed wire and tightly connect wires to terminals. Be careful wires do not place external stress on terminals. Keep wiring in neat order and so as not to obstruct other equipment such as popping open the control box cover. Make sure the cover closes tight. Incomplete connections could result in overheating, and in worse case, electric shock or fire. [ PRECAUTIONS ] 1. Use round crimp-style terminals for connecting wires to the power supply terminal block. (Refer to Fig. 23) If unavailable, observe the following points when wiring. Do not connect wires of different gauge to the same power supply terminal. (Looseness in the connection may cause overheating.) Use the specifi ed electric wire.
